[QUOTE="keep_hope_alive, post: 7079600, member: 576029"] are you saying that a fuse has the exact same resistance as the wire it protects? a fuse has more resistance than the wire it protects #1. #2 every connection you make introduces more resistance. the goal is to minimize resistance for your grounds and power - the entire circuit. we should all agree we are going to fuse the power wire since we have to size the fuse for the wire and protect the car from shorts - you do that on the power wire since the entire car is the ground plane. if we just fuse the ground connection our power wire is not protected. adding more fuses in series adds resistance (both from the fuse itself and the two connections). why do you want to add more resistance to the circuit? resistance causes voltage drop. a difference in potential between grounds is one of the main causes for noise in a mobile audio system. i'm not sure why this is a subject to be combative on.
